It's called Echoes and it's a cross between Asteroids, with a dash of art design from Geometry wars, and some very trippy visual effects.

The basis is simple, it's an arena shooter but with a twist. For one thing, you have a health bar. So it's not like the usual one hit death scenario that's common with arena shooters nowadays. Don't let that fool you though, the game gets incredibly challenging later on, I found myself to be mesmerized by the visuals and dying frequently because of it . It's the very definition of chaotic on the higher stages.

It's a fun game to try out and add to your collection. It's even got achievements if you like that sort of thing.
